VISE AND SAW-CLAMP.

Specification of Letters Patent.

Application filed August 27, 1915, Serial No. 47,696. Renewed July 6, 1916. Serial No. 107,878.

' To all whom it may concern:

portion 3 of the standard 1, as

- Be it known that 1, WILLIAM T. KING, a citizen of the United States, residing at Rosanky, in the county of Bastrop and State of Texas, have invented certain new and useful Improvements in Vises and Saw- Glamps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The general object of this invention is to improve the general construction of vise shown in Letters Patent No. 1,135,815, granted to me April 15, 1915, by increasing the clamping eificiency of the vise and admitting of the operation of moving the clamping jaws of the vise into clamping position and locking the same in the latter position and the unclamping of the jaws, to be performed expeditiously.

Other objects will appear and be better understood from that embodiment of my invention of which the following is a specification, reference being had to the accompanying drawings forming apart thereof, in which:

Figure 1 is a front elevation of the vise, and Fig. 2 is a horizontal sectional view taken on the line 2-2 of Fig. 1.

Referring to the drawings the numeral 1 designates a standard having its lower end beveled, as at 2, and adapted to fit within an opening in a suitable base or support, not shown. The upper end of the standard 1 is provided with an outwardly curved portion 3, the free end of the curved pprtion being formed to provide a clamping aw 4.

Associated with the standard 1, is a lever 5 This lever is pivotally mounted on the standard 1, in scissorsfashion, and at the point of juncture between the standard 1 and the curved portion 3, by means of a pivoted pin 6. The upper end'of the lever 5 is curved in the direction of the curved at 7, and has the free terminal of the curved portion 7 formed to provide a clamping jaw 8, adapted to cooperate with the jaw 4 for clamping articles. The jaw 8 is normally held spaced from the companion jaw 4:, by means of a leaf spring 9. One end of this spring 9 is secured to the standard 1 at a point adj acent the pivot 6, as shown at 10, and the opposite end of the spring 9 extends downwardly and outwardly and engages against the lower terminal of lever 5, and serves to hold the lower end of the lever in the outward position, as shown in Fig. 1, so as to hold the jaws 4t and 8 in normally spaced relation. The lower end of the lever 5 is provided with a block 11, which is located at one side of the lever, and which is held thereto by means of a pin 12, and thesaid pm 12 has connected thereto one end of a link 13, which link engages against the block 11 and said block serves to hold the link spaced from the adjacent end of the lever 5.

The link 13 has its opposite ends pivotally connected to an arcuate shaped link 14, at a point intermediate the opposite ends of the link 1 1, as shown at 15, the said link 14: being arranged in the vertical and having its lower end pivotally connected to the standard 1, as at 16. The upper end of the link 14 has pivotal connection with one end of a horizontally disposed link 17 by means of a pivot pin 18 and the opposite end of the link 11 has pivotal connection with the upper end of a vertically disposed rod 19, by means of a pin 20.

Associated with the standard 1, adjacent the lower ends thereof, is a horizontally disposed foot lever 21. This lever 21 is provided with a goose-neck portion 22. The lever 21 is pivotally connected to the standard 1 at the point of juncture between the A horizontally extending arm 26 has one I end pivotally connected to the standard 1 at a point above the link 17 by means of a pin 27, and the opposite end of the arm 26 is bent downwardly, as at 28, and is provided with an elongated opening 29, which slidably receives the free end of the foot lever 21. The upper side of the foot-lever 21 has formed thereon a series of rack teeth 30, and the upper wall of the opening 29 is formed to provide a pawl 31. Located beneath the foot lever 21 is a locking lever 32. This locking lever 32 has one end pivoted to the lower end of the rod 19 by means of a pin 33 and the opposite end of the lever 32 extends through and is slidably arranged within the opening or slot 29 formed in the downwardly bent portion 28 on the arm 26.

The foot lever 21 has the end which is arranged within the elongated opening 29 provided with a foot rest 34 and the foot rest 34 is provided with an opening thereln which registers with an opening formed in the adjacent end of the locking lever 32. A pin 35 having an enlarged head 36, formed on the upper end thereof, has its stem slidably positioned within the openings in the foot rest 34 and the adjacent end of the lever 32, and has its lower end secured within the opening in the lever 32. When pressure is exerted on the head 36 of the pin 35, that end of the lever 32 which carries the pin is forced downwardly, causing the looking lever 32 to engage the lower wall of the slot 29, and the pressure being continued on the head 36 will cause the lever 32 to draw the arm 26 downwardly, resulting in the pawl 31 engaging in the ratchet teeth 30. By this time the head 36 of the pin 35 engages the foot rest 34, and continued downward pressure will cause the foot lever to move downwardly, resulting in the goose-- neck portion 22 rocking the rod 19 outwardly and through the medium of the various links 13, 14 and 17 will cause the lever 5 to be moved in the direction of the standard 1, whereby to bring the jaw 8 in clamping position with the companion jaw 4 on the standard 1. During descent of the foot lever 21, the pawl 31 will ride over the rack teeth 30, and when pressure is released from the head 36 on the pin 35, the pawl will engage in the teeth 30, resulting in the locking of the jaws 4 and 8 in clamping position. When it is desired to unlock the jaws, pressure is exerted directly on the foot rest 34, causing the foot lever 21 to travel toward the locking lever 32, and drawing the teeth 30 from engagement with the pawl 31.

An expansh'e helical spring 37, has one end secured to a hook 38 mounted on the standard 1 at a point adjacent the curved portion 3, and has its opposite end extending downwardly and outwardly and engaging in an eye 39 carried by the arm 26. When the foot lever 21 is moved downwardly to withdraw the teeth from engage- 'ment with the pawl 31, the spring 37 will draw the arm 26 upwardly and when the pressure is released on the foot lever 21 the spring 37 will return the foot lever and the locking lever to the position shown in Fig. 1, and through operation of the various links, result in the jaws 4 and 8 being moved to unclamping position. The jaws 4 and 8 can be made of any shape desired, and the said jaws have their clamping surfaces provided with serrations, as shown at 40. Auxiliary jaws, shown in dotted lines at 41 in Fig. 1 of the drawings, can be associated with the jaws 4 and 8, so that small articles can be clamped without danger of injury being done the articles.
